All,
I am trying to use workflow-cps-global-lib-plugin to create some custom
classes to be used within pipeline Job for some specific use case
requirement.
Instantiating the custom class within the pipeline Job. However anything
logged within the our custom class is not posted in the Jenkins console.
As a hack, I have tried sending the Listener of the build to the custom
class and logging it to it which solves the issue of messages not appearing
in the console. However, message get jumbled up and down, as every step
within the pipeline is executed in separate context and the log messages
sent to from custom class ends up on top of all the messages, which defeats
the purpose. see example below.
Is there any other alternatives that we could potentially use, such as
creating a workflow step to execute the methods of our custom class, which
passes the listener from the correct context.
Appreciate any suggestions, that could help us get over this hurdle as we
are running tight timelines to this done. Thanks for your help.
Here is the sample code;
In Pipeline job definition:
def custom_class = new CustomClass(currentBuild.getRawBuild())
echo "starting Master"
custom_class.test_log()
echo "Test Echo"
CustomClass, logger is defined as below.
class CustomClass {
def jenkins_logger
CustomClass(rawbuild) {
this.jenkins_logger = rawbuild.listener.getLogger()
}
def test_log(msg) {
this.jenkins_logger.println(msg)
}
}
